Yes. The key is to treat decarbonization as a measured baseline + forecast + scenario model + actual-vs-plan tracking problem.
A practical framework is:
For example:
| Scenario | Renewable electricity | Efficiency | Result |
|---|---|---|---|
| Business as usual | 0% | 0% | 100% baseline |
| Moderate | 50% | 10% | ↓ emissions |
| Aggressive | 100% | 20% | ↓↓ emissions |
| 100% + storage | 100% | 20% + storage | ↓↓↓ potentially |
The important part is to model cost, emissions reduction, timing, and operational constraints together, rather than simply assuming that "100% renewable" equals zero emissions.
There are several good options, depending on how sophisticated you need the model to be.
This is probably one of the strongest enterprise-oriented choices.
IBM's current solution combines ESG/emissions data from Envizi with Planning Analytics for forecasting and scenario modeling. It explicitly supports what-if analysis, emissions baselines, reduction strategies, and comparison of business-as-usual/best-case/worst-case scenarios.
Good if: you want sustainability modeling integrated with finance and operational planning.
SINAI is particularly focused on decarbonization planning rather than just ESG reporting. It lets you model projects, costs, savings, emissions impacts and ROI, compare different decarbonization pathways, and then track actual project performance against the plan.
Good if: the question is "Which projects should we actually fund to hit our carbon target at the lowest cost?"
Coolset offers scenario planning across Scope 1–3 and lets users test different reduction pathways. Its scenario builder specifically supports changing variables such as fuel types, quantities, transportation and renewable-energy usage.
Good if: you want a relatively accessible carbon-management platform with scenario planning.
Cozero's ACT platform goes further into the financial side: you can simulate "what-if" switches, calculate ROI/payback/NPV/IRR and marginal abatement cost, and track approved actions against budget, timeline and emissions impact.
Good if: you need to make the business case to a CFO or investment committee.
WattTime is a little different. It's not primarily a corporate decarbonization-management platform; it provides granular electricity-grid emissions data that can make your renewable-energy scenarios much more realistic.
Its data includes marginal and average grid emissions, historical data and forecasts across 200+ countries and territories.
This matters because where and when you consume/procure electricity can affect the actual emissions avoided. For example, WattTime can model the marginal emissions associated with electricity consumption and assess where new renewable generation is likely to displace more fossil generation.
If your primary question is:
"We consume X MWh of electricity today. What happens to our emissions, cost and trajectory if we move 25%, 50%, 75%, or 100% to renewable electricity?" I'd structure the model around these variables:
Electricity demand × grid emissions factor + renewable procurement + on-site generation + storage + timing/location
Then produce, for every scenario:
For a sophisticated implementation, SINAI or IBM Envizi/Planning Analytics + WattTime data would be a particularly powerful combination: the first layer manages the corporate decarbonization roadmap, while the second gives you more realistic electricity-emissions assumptions.
If you tell me your industry, approximate annual electricity consumption, geography, and current renewable-energy percentage, I can also sketch a concrete renewable-energy "what-if" model (including the variables, equations, scenarios and dashboard KPIs) that you could implement in Excel/Power BI or one of these platforms.

Tracking decarbonization progress and running "what-if" scenarios for renewable energy transition spans a few different levels—from corporate carbon accounting to macro-level power grid optimization.
If you are tracking corporate or institutional footprints and want scenario simulation capabilities:
If you need to model power systems, hourly renewable integration, and capacity switching, researchers and engineers rely on specialized energy modeling platforms:
Are you looking to model an entire regional power grid/country , or do you need a tool focused on a single corporate/industrial portfolio?
Yes. Organizations typically track decarbonization progress by combining carbon accounting, target tracking, energy data, and scenario modeling. A good platform should answer both:
Key capabilities include:
A few categories of platforms can do this:
IBM
Combines ESG data with forecasting and scenario modeling.
Supports comparing emissions reduction pathways, including business-as-usual and alternative reduction scenarios.
Watershed
Focuses on measuring emissions, identifying reduction levers, planning pathways, and tracking progress.
Includes scenario planning for energy procurement and emissions reductions.
SINAI Technologies
Built specifically around decarbonization roadmaps, marginal abatement cost curves, project prioritization, and scenario comparisons.
Useful when you want to compare emissions impact versus cost.
Current state
Scenario A: Renewable PPA
Scenario B: Onsite solar + battery
Scenario C: Full renewable transition
For most companies, I would prioritize:
| Capability | Why it matters |
|---|---|
| Scope 1–3 carbon accounting | Establishes a defensible baseline |
| Renewable energy modeling | Tests solar/PPA/storage options |
| Scenario comparison | Enables “what-if” decisions |
| Cost modeling | Connects climate plans to finance |
| Project tracking | Shows whether reductions actually happen |
| Audit trail | Supports reporting and assurance |
If your focus is specifically switching electricity supply to renewables, energy-system tools like HOMER Pro may be more useful. If you need a corporate net-zero roadmap tied to budgets and emissions targets, platforms like IBM Envizi, Watershed, or SINAI are closer fits.
We track decarbonization progress by measuring greenhouse gas emissions against established baselines, using standardized accounting frameworks like the GHG Protocol (Scope 1, 2, and 3 emissions) and real-time data integration.
Yes, there are specialized carbon management and energy transition software platforms that allow organizations to model "what-if" scenarios . These tools simulate switching to renewable energy sources, changing supply chains, or electrifying operations to project future emissions trajectories.
Platforms for Tracking & Modeling
| Platform | Core Focus | What-If Modeling Capabilities |
|---|---|---|
| Terrascope | Enterprise carbon accounting & reduction | Simulates business-as-usual vs. reduction pathways, assessing alternative reduction strategies over time. |
| Carbonfact | Product & corporate carbon footprinting | Runs real-time "what-if" scenarios for switching suppliers, materials, and scaling renewable energy. |
| Ecochain | Life Cycle Assessment (LCA) & manufacturing | Automates facility-level tracking to analyze the impact of swapping to wind, solar, or efficient processes. |
Key Methods Used in Tracking & Simulation
If you'd like, let me know:
Yes. Organizations typically track decarbonization progress through a combination of carbon accounting, emissions dashboards, and decarbonization pathway modeling. Modern platforms can do more than report historical emissions—they can simulate “what-if” decisions such as “What happens if we replace grid electricity with renewable PPAs?” or “What if we electrify our fleet by 2030?”
A typical system tracks:
Baseline emissions
Targets and pathways
Operational metrics
Financial alignment
Here are examples of platforms that include scenario modeling:
| Platform | What-if capabilities |
|---|---|
| SINAI Technologies | Models reduction projects, costs, savings, ROI, carbon impact, and compares alternative decarbonization pathways. www.sinai.com |
| IBM Envizi with Planning Analytics | Combines ESG data with forecasting and scenario modeling; supports testing emissions reduction strategies. www.sinai.comwww.ibm.com |
| Watershed | Helps organizations model reduction paths, including clean power decisions and energy procurement scenarios. watershed.com |
| Pulsora | Provides emissions forecasting, pathway modeling, sensitivity analysis, and scenario testing. www.pulsora.com |
| S&P Global Energy Scenarios | Provides energy-transition scenario analysis, including renewable penetration, electrification, energy demand, and emissions pathways. www.spglobal.com |
| ClimateView | Focused on transition planning with scenario forecasting, intervention assessment, and progress monitoring. www.climateview.global |
A decarbonization planning platform might let you compare:
Scenario A — Business as usual
Scenario B — Renewable electricity transition
Scenario C — Electrification pathway
Scenario D — Accelerated net-zero pathway
For a company specifically evaluating renewable energy switching, I would look for a platform that can connect:
That combination turns decarbonization from a reporting exercise into an investment planning model.
Tracking decarbonization progress and modeling "what-if" scenarios for renewable energy adoption involves two closely related steps: carbon accounting/management (measuring where you are and tracking progress) and energy/transition scenario modeling (simulating future shifts to renewables).
Depending on whether you are tracking a single building, an enterprise supply chain, or an entire regional grid, different platforms cater to these needs:
If your goal is to track organizational emissions (Scopes 1, 2, and 3) and model reduction pathways or renewable energy transitions:
If you are looking to model large-scale "what-if" scenarios for shifting entire grids, cities, or industrial sectors to renewable energy sources:
To help narrow down the best platform for your specific goals, let me know:
Yes. The key is to treat decarbonization as both a measurement problem and a scenario-planning problem.
A useful system tracks at least four layers:
| Layer | What to track |
|---|---|
| Baseline | Scope 1, 2 and relevant Scope 3 emissions; energy consumption by site/fuel |
| Targets | Absolute tCO₂e reduction, emissions intensity, renewable-energy % and interim targets |
| Actions | Solar, PPAs, renewable-energy procurement, electrification, efficiency projects, fleet changes, etc. |
| Actual results | Expected vs. realized CO₂ reduction, energy/cost savings, project status and investment |
For renewable-energy switching specifically, I'd track MWh consumed → MWh renewable → emissions factor → tCO₂e avoided, while keeping location-based and market-based Scope 2 accounting distinct.
There are several good options, but they serve somewhat different purposes.
Best fit for an enterprise decarbonization program:
For a deeper question like:
"What happens if we replace 60% of our grid electricity with solar + wind + storage by 2035?"
I'd look beyond conventional ESG reporting software.
S&P Global Integrated Energy Scenarios has particularly sophisticated scenario capabilities. It allows users to change assumptions such as renewable penetration, electrification, energy efficiency and carbon prices, and its scenario builder can incorporate custom time-series assumptions for renewable power, energy prices, electrification, etc.
For a more open/research-oriented approach, Energy Transition Model is an open-source modeling platform where you can construct future energy scenarios and explore pathways through 2050.
The EPA's AVERT is another useful U.S.-specific tool for estimating how renewable-energy and other electricity programs affect emissions. It can model user-created future scenarios, although it's more focused on the electricity system than enterprise-wide corporate decarbonization.
If you're evaluating this for a company, I'd structure the platform around a scenario engine like:
Current baseline → proposed intervention → energy impact → emissions impact → financial impact → target trajectory → actual vs. forecast
For example:
Baseline: 100,000 MWh electricity/year
Scenario A: 30% renewable electricity by 2030
Scenario B: 70% renewable electricity + efficiency
Scenario C: 100% renewable electricity + electrificationFor each scenario: tCO₂e avoided + $ cost + CAPEX + OPEX + renewable MWh + payback + progress toward 2030/2050 target
That gives management something much more useful than a carbon dashboard: "If we spend X, do Y, and switch Z% of our energy supply, where will our emissions be in 2030?"
If you tell me whether you're thinking about a single company/facility, a portfolio of facilities, or a city/utility, I can narrow this down to the 3–5 best platforms and compare their scenario-modeling capabilities, data requirements, and approximate cost/implementation complexity.
Tracking decarbonization progress and running "what-if" scenario models depends heavily on your scale—whether you are looking at the entire globe, a municipality, an industrial sector, or a specific corporate enterprise.
How Decarbonization Progress is Tracked
Progress is generally measured through a combination of national inventories, independent remote sensing, and corporate carbon accounting:
Platforms for Modeling "What-If" Renewable Scenarios
Several advanced software tools and platforms allow you to simulate energy transitions, evaluate cost structures, and model renewable energy switching:
If you can share what scale you are modeling (e.g., a specific facility, a corporate supply chain, or a regional grid) and your preferred technical depth , I can recommend the most suitable tool or framework for your project.
Yes. The key is to treat decarbonization as a measurable operating plan, not just an annual ESG report.
I’d use a dashboard with five layers:
Baseline emissions
Energy transition
Reduction pathway
Decarbonization initiatives For each project—solar, renewable-energy procurement, electrification, efficiency, fleet transition, etc.—track:
Scenario analysis This is where the platforms below become particularly useful. You can ask questions such as:
"What happens to our Scope 2 emissions and energy costs if 50% of our electricity becomes renewable in 2027, 75% in 2028, and 100% in 2030?"
Microsoft Sustainability Manager is a particularly direct fit for your question. Its What-If Analysis capability can model the emissions impact of business changes, explicitly including switching electricity to wind or solar. Microsoft says the feature can layer up to three strategies within a scenario.
SINAI is another strong option if you want more sophisticated decarbonization planning + financial analysis. It combines scenario modeling, project-level emissions and financial modeling, marginal abatement cost curves (MACCs), roadmaps, carbon-price sensitivity, and tracking of planned vs. realized reductions.
Watershed is especially interesting if renewable-energy procurement is a major part of the strategy. It supports scenario planning for future energy costs/procurement, models emissions impacts, tracks progress against targets, and supports clean-power procurement including VPPAs and onsite solar.
Persefoni combines carbon accounting with Net-Zero Navigator, which generates customized decarbonization scenarios and recommendations and tracks progress against targets. Its earlier reduction-modeling capabilities specifically included energy-transition modeling at the facility level, allowing users to model the effect of switching electricity to clean sources.
| If your priority is… | I'd look first at… |
|---|---|
| Microsoft ecosystem + straightforward what-if modeling | Microsoft Sustainability Manager |
| Detailed decarbonization strategy + financial ROI | SINAI |
| Renewable procurement + corporate footprint management | Watershed |
| Carbon accounting + target/pathway modeling | Persefoni |
The important distinction is that carbon accounting software tells you where you are; a decarbonization platform should also let you test where you're going.
For example, I'd want to be able to create scenarios like:
Baseline → 25% renewable electricity → 50% → 75% → 100%
and have the platform automatically show, for each scenario:
tCO₂e reduction + % reduction + energy cost + implementation cost + target-year gap + ROI/$ per ton avoided.
That gives management an actual decision model rather than just a sustainability dashboard.
If you tell me your organization type (manufacturing, real estate, data centers, healthcare, etc.), approximate number of facilities, and whether you're mainly concerned with Scope 1/2 or Scope 1–3, I can narrow this to the 2–3 platforms that are most appropriate and compare their scenario-modeling capabilities.
Tracking decarbonization progress and modeling renewable energy transition pathways relies on a combination of enterprise carbon accounting software, global satellite-and-asset tracking databases, and specialized energy system modeling tools.
Part 1: How We Track Decarbonization Progress
Decarbonization tracking occurs at multiple levels—from individual corporate value chains to entire nations:
Part 2: Platforms for Modeling "What-If" Scenarios (Renewable Transition)
If you want to simulate switching to renewable sources, altering grid mixes, or adjusting carbon prices, several robust platforms and open-source models fit different scales:
Are you looking to model a specific organization/facility or a whole regional/national grid ? Let me know and I can recommend the most appropriate platform or open-source tool for your exact use case.
